The reference site the brainrot community deserved but nobody had built yet.
Steal My Brainrot is a comprehensive reference site for two of the most popular brainrot games right now: Steal a Brainrot on Roblox, made by SpyderSammy, and Steal the Brainrot on Fortnite Creative, made by Ferins with an official license from SpyderSammy.
The brainrot universe started as a wave of absurdist AI-generated meme characters, things like a shark with Nike shoes or a crocodile fused with a bomber plane, that exploded across TikTok and YouTube. SpyderSammy turned that energy into one of the most addictive idle games on Roblox, and Ferins brought it to Fortnite. Both games have massive, passionate communities and almost no good reference tooling. That gap is what this site exists to fill.
Every brainrot character from both games lives here. Each entry includes the character name, rarity tier, income per second, and a description of what the character actually is. The Roblox game spans eight rarity tiers from Common all the way up to the almost mythically rare OG characters, with income values that span many orders of magnitude between them.
Character pages let you look up any brainrot by name or browse the full list filtered by rarity. When you are standing at the conveyor wondering what you just got, or arguing with your friend about whether a Secret is worth more than three Brainrot Gods, this is where you come to settle it.
The tools are where this site does something no brainrot resource has done before. We built a full suite of calculators that model the actual math of the games.
The Income Simulator lets you build out your entire base slot by slot, choosing a character, mutation, and traits for each one, then selecting your rebirth level. It computes your total income per second, shows you which slots are pulling their weight and which are dragging the team, and projects your earnings over time.
The Rebirth Optimizer answers the question every mid-game player obsesses over: should I rebirth now or keep farming? It takes your current income, your coin balance, and how much time you play per day, then tells you exactly when the math tips in favor of rebirthing and how long it will take to recover.
The Trait Calculator stacks mutations and traits multiplicatively and shows you the combined multiplier you are working with. The Fuse Simulator shows the community-verified probability breakdown for any rarity combination you put in. The Spawn Visualizer shows you exactly what the luck multiplier actually does to your odds across every rarity tier.
The Upgrade ROI tool ranks every character in the game by income earned per coin spent, filtered to what you can actually afford. It is the fastest way to answer "what should I buy next."
Some of the most valuable moments in Steal a Brainrot are time-gated. The Molten Event is the only window where Lava mutations, one of the highest multipliers in the game, can spawn, and it only lasts fifteen minutes at a time on a repeating cycle. Admin Abuse events happen on a weekly schedule and are when admins drop rare and secret characters directly into the game.
We built live countdown timers for both, an event calendar that shows everything on a single page with per-event countdowns, and an iCal export so you can add brainrot events to your actual calendar like a person with priorities.
The Fortnite version of the game is almost completely unserved by existing tool sites. Almost every resource out there is focused on the Roblox version, and the few that mention Fortnite mostly just list the map code and move on.
We built a full active code database for the Fortnite version, with one-click copy, reward type labels, and status tracking so you know which codes are still working. The Code Optimizer filters that list by what you actually need. If you are looking for a luck boost specifically, it shows you only the codes that give that. The Fortnite Rebirth Table gives you the same clean level reference that Roblox players have had for a while.
This one is just fun. The Lucky Pull Simulator uses the real spawn weight data from the game to simulate hundreds of conveyor pulls at whatever luck multiplier you choose. It shows you the breakdown of what you got, displays the results as a grid of colored dots, and generates a shareable URL so you can send your results to friends. Because sometimes you need to prove that you have gone five hundred pulls without a single Secret.
Both games exist because of specific humans who made specific creative decisions. SpyderSammy built Steal a Brainrot from the ground up and created the template that the whole genre runs on. Ferins licensed it and brought it to Fortnite Creative, where it broke records for concurrent players.
We have profile pages for both creators that tell the story of how these games came to be and link you to their work.
If someone is new and trying to figure out whether to start on Roblox or Fortnite, the Which Version quiz walks them through five questions about their platform, playstyle, and preferences and gives them a recommendation with a reason. It is a small thing but it answers a question that comes up constantly in the communities.
The site is live and growing. Coming soon: a price history tracker for trade values, a community trade board, a cross-game character comparison showing which characters appear in both versions, a full Fortnite income calculator, and a collection tracker so you can mark off which characters you have obtained.
The character database is the ground truth and we keep it current as the games update. If something is wrong or missing, the best way to flag it is through the GitHub link below.
